New commenting features being tested

Hi, all. I’m trying out some new commenting features here on the blog, including using Facebook and Twitter to log in. Things might work a little strangely for a while, but I hope this will go smoothly. I’ll be making changes as needed.

(Earlier I tried logging in through Facebook and it looked as if it didn’t work, but when I reloaded the page, it showed it had worked after all. Please let me know if you run into the same issues, or any other problems. Thanks!)
